DESCRIPTION

The
strchr()
function returns a pointer to the first occurrence
of the character
c
in the string
s.

The
strrchr()
function returns a pointer to the last occurrence
of the character
c
in the string
s.

The
strchrnul()
function is like
strchr()
except that if
c
is not found in
s,
then it returns a pointer to the null byte
at the end of
s,
rather than NULL.

Here "character" means "byte"; these functions do not work with
wide or multibyte characters.

RETURN VALUE

The
strchr()
and
strrchr()
functions return a pointer to
the matched character or NULL if the character is not found.
The terminating null byte is considered part of the string,
so that if
c
is specified as '\0',
these functions return a pointer to the terminator.

The
strchrnul()
function returns a pointer to
the matched character,
or a pointer to the null
byte at the end of
s
(i.e.,
s+strlen(s))
if the character is not found.
